Jessica Chastain wore a Givenchy Fall 2011 dress to the event - I'm totally digging this high neck, pure white dress with beading. It looks beautiful with her hairstyle and those large pearl earrings.

Elle Macpherson was another celebrity to wear a Zac Posen gown. The ivory coloured taffeta & tulle dress looked great on her, unsurprisingly. She wore it with loose locks and Lorraine Schwartz baubles.
